AUTOMOBILE-WHEEL AND RIM.

Specification of Letters Patent.

Patented July 29, 1913.

Application led December 2, 1912. Serial No. 734,500.

To Cdl 10k-0m t may concern.'

Be it known that I, GUsT P. PAPPADAKES, a subject of the King of Greece, residing in the borough of Manhattan, in the city, county, and Sta-te of New Yorn have invented certain newand useful Improvements in Automobile-Theme and Rims, of which the following is a specification.

The invention relates to wheels and rims,

and one object of the invention is to con-V struct an automobile Wheel which permits the ready removal therefrom and the ready 'replacement thereupon of a pneumatic or other yieldable tire.l

Another object of the invention is to construct a rim which Will comprise outer rings or tire retaining annular sections which can be clamped tightly together by members passing therethrough.

A further object of the invention is'to provide a pair of tire supporting and retaining rings with a spring means that nor -mally presses them apart and with means for holding them detachably secured together.

Another object of the invention is to provide a wheel with a flanged abutment on one side face of the Wheel and with a latch or latches on the other side face of the i I right a wheel for locking between the flanged abut- 'nient and the latch or latches a pair of tire holding sections which are normally pressed apart by strong spring means therebetween.

The invention also relates to other features which together with the features above enumerated are clearly set forth in the appending claims.

As showing a specific embodiment of the invention, reference is made to the drawing forming a part of this specification, in Which- Figure l is a side vieW of a Wheel par` tially broken away with the tire retaining rings in place thereupon. Fig. 2 is a view showing at thelcft a section` taken on the line 2a-2a of Fig. l, looking in the direction of the arrows (L a, and-showing at. the section taken on the line Qb- Qb of Fig. l, looking in the direction of the arrows and Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1.

The body or inner main-portion of the Wheel, which is generally made of Wood, is

designated by the reference character A and comprises the usual hub B, the spokes C, and the felly D. An inner metal ring E is secured to the wooden felly D as by the screws c. A pairof outer annular rings F and -G'tit on and over the inner metal. ring E and are detachably secured in place by the clamping means comprising the inner clamping plate H. the bolts l andl and theouter clamping plate L. It Will be manifest from an inspection of the drawings that the outer rings serve to support, to retain and to hold the tire in place on the wheel.

The inner side or face of the wheel is provided with an annular ring or fiange member M which serves as an Between the outer rings G and F there are provided compression Vsprings vH which tend to normally press the ring sections Gand F apart. ln order to facilitate the assembling et' the outer rings G and F in place on the'wheel so that they may be held in substantially the linal position prior to drawing tight the bolts in the clamping means, there are provided the latches O O which'are bolted to the wooden fcllv D at O-O2. The movable ring engaging meinbers 03 of the latches are normally pressed radially outwardly by the spring O* and can be clamped in their outer position by the nut or thumb screw member From an inspection of the right hand end of Fig.

-2 and also from an vinspection of Fig. l it will be apparent that the outer end of the movable ring engaging latch 'member O3 enters a recessed portion F of the ring. lt will also be observed that these movable latch members O3 can hold the outer rings between the abutment fiangc- M and said latch members, while the bolts in the cla1nping means are either being tightened or loosened. It will furthermore be noted that the clamping bolts K pass through the wooden portion of the wheel and secure the inner and outer clampingplatesA H and L in place on the inner and outer faces of the wheel and that the clamping bolt K passes through the saine two )lates and also through'the lugs G2 and T2 which are on the respective outer rings G and F. Thus this bolt K can serve to draw the plates ll and K together whereby they can clamp therebetween the inner and outer rings and thus press the latter tight-ly together.

The lugs F2 and G2 just referred to-ex- 4tend radially inwardly abutment for the outer ring G when inv place on the wheel.

and enter the reeoI eessed portions X-X in the inner or body portion A of' the wheel. From an inspection of Fig, l it.- nill be observed that the inner metal ring ll is provided with depressions ai ttwse recessed p .ii-tions X.X, into wlieh depression the hiigs F2 and G2 tit.

lthe improvements herein set lorth are notl limited to the precise eonstrut'ition and arrangement shown and described, as the),7 may he en'ibodied in various 'lornis and modifications withmit departing: from the .spirit and scope of the invention.

What l rlaim is: A

l. in an automobile wheel the combination et an inner member havingl a seat. for rei-ehing thereupon outer annular 'ire engaging' and holding rings and also a tlanged abutment which one of said rings engiges, the outer tire holdingr or tire engaging rings thus ,referred to, springs between and engaging the tire holding' rings tendini; to normally press said rings apart, a spring` latehing means on the opposite side of the wheel :from that upon which the .langed abutment is located for locking' the ring-:z in place between the abutment and said late-h'- iutr means and means comprising bolts and damping plat.esfor holding the tne engaginefseetions in place.

ln an automobile wheel the combination of an :inner member having` a seat for reeeiring thereupon outer annular tire holding rings and also a flanged portion against which one of said rings abuts, said outer tire holdingf or tire `engaging rings, compression springs between the tire holding" sei'tions tending,r to normally press theni apart, said springs being located outside of said metallic seat, spring latehing means on the opposite side of the wheel from that upon which the Ilanged portion is 'located [or looking' the rings in place between the flanged portion and latehing means, and

means Comprising bolts and clampingl plates tor drawing the tire engaging sei-tions tightly together, at least part otA said bolts passing through lugs on each tif-said tire engaging rings, which. lugs extend radially inwardly.

In combination, .a pair of annular tire supporting and retaining rings which engage the outer shoe of the tire, a -compression spring between said rings, and meansv eomprising bolts .for clampingsaid, rings together, said rings each having lugs in.- tegral therewith that extend radially inwardly, theeompression spring being, loeated between said lugs, and at least apart ot' the bolts passing' through said lugs.

l.. An automobile wheel having an inrfr member, annularI tire engaging` outer rings titting; on 'and over said inner member, said inner member being provided with depressions into whit-h lugs on said tire engaging rings enter, compression springs between said lugs tending to normally force the tire engaging' rings apart, a id means for vClamping` said tire engaging rings in place on said inner meml'ier, said clamping means comprising plates that engage both the inner member and the lugs of the tire engaging rings .and also comprising bolts which pass from the plates on one side of the`--wl1eel to the plates on the other side oithewheeland through said lugs, said clampingr means also eomprising other bolts that pass Vt'rom'the plates at one side of the wheel to the plates en the other side of the Wheel through inner member of the wheel.

This specification signed and witnessed this 26th day of November, A. AD. 1912.
